Why Life Cycle Assessment? <ul><li>LCA is a systematic approach to measuring the environmental performance of products </li></ul><ul><li>LCA compiles and evaluates the inputs and outputs of a product across its life cycle </li></ul><ul><li>LCA creates added value through product “ecolabeling”, marketing initiatives, and product comparisons </li></ul><ul><ul><li>Software Package: GaBi 4.0, PE International </li></ul></ul>

Methodology for identifying opportunities to “ green ” the existing supply chain <ul><li>Use LCA results to examine specific phases of the supply chain in detail: </li></ul><ul><ul><li>Compared the environmental performance of individual materials on a kg-to-kg basis </li></ul></ul><ul><ul><li>Identified “hot spots” along the supply chain based on increased environmental performance and supply chain control </li></ul></ul><ul><ul><li>Co-evaluated the environmental performance of materials and their relative economic cost on a kg-to-kg basis </li></ul></ul>

27.
Analyzing the Supply Chain Targeted Actions - Results <ul><li>Identified three “hot spots” along the supply chain where environmental performance is poor and Simple has a moderate-high degree of control over this actor/process? </li></ul><ul><ul><li>1. Composition of Shoes (Material Dependent/Absolute) </li></ul></ul><ul><ul><li>2. Footwear Manufacturing Process (Moderate/High) </li></ul></ul><ul><ul><li>3. End of Life Management (Poor/Moderate) </li></ul></ul>

Conclusions <ul><li>Is a green toe shoe “ simply ” better in terms of environmental performance than their other footwear products, based on the scope of analysis? </li></ul><ul><li>YES </li></ul><ul><li>Green Toe shoe (1) has a lower impact in 8 of the 10 environmental impact than the conventional shoe (4) </li></ul><ul><li>The Green Toe shoe performed best across the two most significant impact categories: Toxicity and GWP. These represent the largest fraction of global emissions across the impact categories </li></ul><ul><li>The only difference in the supply chains of the Green Toe and the conventional shoes is the material choices and the materials production phase has the greatest impact </li></ul><ul><li>Green Toe requires the least redesign for composting which is the recommended EoL option </li></ul>
